Network equipment to study energy saving server

Network equipment to study the energy savings server

After the introduction of energy management, server, recording the user to access a avalanche of praise. At the same time, the network equipment is also working to achieve the level of power savings server. HP ProCurve Networking products sector, said manager products Dale Cosgro, the network equipment manufacturers emphasize the computer last year, saving features, the title of saving energy = "A1189 Laptop Battery Apple"> Apple A1189 battery of the previous teams did not cover too.

The overall energy consumption, server or network infrastructure storage and can not at the same level. Although over switch, the server consumes more energy, but the network represents 15% of the energy budget. The server has a sophisticated control of power management, and the server is a different network equipment must be ready to receive information.

network switch lattice energy consumption is enormous. Cisco Catalyst 6500 Series switches 42U architecture for each power 2 kW to 3 kW. Cisco Advanced Services Group, said architect Rob Aldrich, Cisco Systems, the largest enterprise level switch – Nexus 7000 Switches Series in the power of each architecture to 13kW. A structure of power switches generate 13kW of heat on a number of servers rack-mounted, which is concerned about the cooling of the server.

Research firm Gartner Inc., said the analyst Rakesh Kumar, compared to most server racks of data center power 8kW to 10 kW. Vice President of Hewlett-Packard and General Manager of the key equipment, "said Peter Gross, the power of the current average 4 kilowatts per rack.

Some manufacturers have begun introducing devices saving energy, such as high efficiency power supplies, variable speed fan. But now, in the area of the switch, management measures taken by the power very limited. Most of inactivity to switch operating the most energy 40% to 60%. Aldrich said that if less than 40%, then change the operation must be updated. He said: "unless the user can accept delay, if you consume lots of energy. "

Cosgro But the largest increase is imminent.

More efficient technology

energy efficiency technologies support is gradually improved in several areas related to the other. Cosgro has said: "As a new generation of flagship products to open the market, have the following characteristics. "For example:

@ There will be more modular application specific integrated circuit (ASIC) designs the switch to turn off the light LED on the panel to the table memory, which does not use the component.

Advances in silicon technology @ will reduce leakage current, and little by little to promote energy conservation through a new generation of chips. Cosgro said: "Ultimately, we will let network equipment for the daily power consumption of 100 watts to 10 watts.

@ I + D has a backup software energy efficiency, the software will use less energy efficient CPU title = "Dell Inspiron 500m battery"> Dell Inspiron Resource 500m battery, and less power.

@ It is designed to operate at high temperatures of the equipment reduce cooling costs.

For example, the current Cosgro ProCurve equipment can be safely performed on 130 degrees, the temperature gauge is much more than the goal of most data centers. He said: "As data center managers hope to be able to operate at high temperatures, so this need to promote this design. "

temperature operation may be higher in the wiring inside there is a single supplier. However, the temperature around 130 degrees before being considered, especially in the center rack of data network equipment providers have to do in a mixed environment of comprehensive tests. Burton Drue Reeves Group analyst said: "When all the servers can exchange more heat to come, nobody knows network equipment and other equipment will be shown how. "

The current data for each vendor is limited to its own production team.

Another Objective: increasing the area of power control and more precise control. For data center, the real power and temperature control is the key, but also improve species management. Accenture consulting firm dedicated to the practice of Rockwell Bonecutter Green IT, said: "If something is not normal, you want to know before the disaster."

Management software will be configured for identification specific network devices such as IP phones configured at Discovery Protocol link. The software can automatically during the day or certain times of day when the computer shuts down after the relevant cut off current VoIP devices over Ethernet.

Other examples: in the day, as a dismissal on the edge switch associated with the two routers, but at night, the network can be configured as a router in a standby mode at low power. Only when necessary, the second router awoke.

Cosgro said: "This kind of applications represents a savings opportunities. "

Staff rules

To support new energy efficiency standards in the network is idle, to help measure the energy efficiency of competing products.

Energy efficiency Ethernet

Emerging energy efficiency P802.3az IEEE Ethernet (EEE) equipment, the draft regulation may be the case as = "HP Pavilion dv9000 battery"> HP Pavilion dv9000 battery low utilization rate of maximum degree of reduction of energy consumption of network devices. Ethernet device currently ongoing transmission between two devices, even when the network is always the case when no information. The support team of ESA to send periodic pulses, other Again silence. In my free time, this technology can reduce energy consumption by 90%.

Cosgro said that in large networks, this will save much energy.

The new rule also allows multiple operating mode switch. For example, in a switch 10 Gb, if circumstances permit, individual ports can be 10 Gb per second by the second transfer rate has been reduced to 1 Gbps, to save energy.

Aldrich said that in 2011, support ESA standard equipment on the market.

Virtual LAN

A Another emerging technology is the PCI-SIG has released the multi-source I / O virtualization (MR-IOV), your server in a rack of Network Interface Card provides access pool. Broadband PCI Express, which essentially extend the PCIe bus outside of the server. Burton Group analyst, Reeves said: "Instead a server in each network card, a card rack. You can use the server tools providers assigned to a server in one of these cards were part the bandwidth of the network card. "

using the lattice energy increases, which is a virtual network bandwidth card each segment achieved. He said that technology allows a network card and a few ports on the switch. Reeves prognosis appears first line of products 2012.

Energy efficiency

Finally, the standardization of energy efficiency measures began appear in a number of network devices. For example, the Juniper Networks products are some of its energy consumption rate (ECR) form data. ECR is a draft standard, proposed by the initiative, Rec. Lawrence Livermore Laboratory, Ixia and Juniper improve the specification, measurement and network communication equipment for each unit of energy performance.

Cisco and Juniper has also begun to support the standard Industry Telecommunication Union (ATIS) IBM ThinkPad T60 telecom energy efficiency rating of the battery (Teer) specifications. Specifications for ATIS last year.

But every rule is not universally accepted. While Juniper P. support, but not all forms of product data are included in the index of efficiency. Cosgro said that because HP can not understand the scope of the user, the HP data in the form of its products containing these energy efficiency standards. He said: "Users recognize the power of a large number of solutions. "

Cosgro said that currently still exist outside of these rules, opposition, opponents to the conclusion that the absence of detailed classification system and transparent. This means that manufacturers can choose meet the needs of your score.

Until later this year, may be introduced rules truly transparent. Over time, the EPA standards for large teams of network Energy Star be published. Before last December, the EPA has developed the Energy Star specifications for equipment small network, the network specification for the next big teams covered most of the network devices.

As the spokesman of the EPA said it intends to publish in June 2010 a draft standard on data centers, announced the end 2010, the network devices in data centers in the draft regulation. Cosgro said the new rules include the provision of energy, internal energy efficiency of chips and other components as well as Ethernet and the total energy consumption of the equipment will become an energy significant future efficiency standards.

For network administrators, to provide energy efficiency is the way easier to buy new equipment, but the reality is a gradual process, because an administrator must update the old equipment to measure costs and benefits of the potential energy of the relationship.

QUESTION network card?

I have a problem. Then you have a LAN card coupled to a Pci Network Card on the same PC? One is for DSL and the other will be used for the network .. I try to connect a PC to PC using a crossover cable .. Help! important detail: NO POWER HUB or router. only two PCs are involved .. crossover cable is used .. Thank you guys! everything I need to know is that, if possible, and all the answers were great! best answer goes to the last guy, however, gave a new and useful information .. Indeed, the problem I was having I was an IRQ conflict, so just put the card in another PCI slot reallocation .. IRQ that was to solve the problem ..

Yes, it will work. You should be able to share the Internet connection between the two teams too. What version of Windows you use depend on time or not can not be used as a DHCP server. Windows 2000 Server or Server 2003 that would transform it into a PCI network router. You can have multiple cards network. In the new equipment, do not even need a crossover cable. All you have to do is go into the properties NIC and assign an IP address (192.168.0.1 and 192.168.0.2 as the other, and set the default gateway IP address of the machine (one Internet ))… Good luck, you can message me on yahoo or send me an email if you need too ..
